Description

Lighting device and lamp comprising same
Technical Field
The present application relates to the field of lighting technology, and more particularly, to a lighting device using an integrated optical member including a light transmission part and a sealing part, which is prepared by co-extruding hard and soft materials, and a lamp including the same.
Background
Lamps using Light Emitting Diode (LED) chips have the characteristics of high light emitting efficiency, power saving, and long life, and thus are increasingly widely used. However, since the temperature of the LED chip itself will rise continuously when the LED chip emits light, if the heat generated by the LED chip cannot be dissipated out in time during the continuous lighting operation, the LED chip will be damaged. Therefore, the heat dissipation problem of the lamp using the LED chip has been a concern in the industry.
In addition, due to the sensitivity of the LED chip to moisture and humidity, if the lamp envelope of the LED lamp is poor in water and moisture permeation resistance, the possibility of failure of the LED lamp is increased.
In the conventional general LED lamp shown in fig. 1, the housing of the LED lamp is made in one piece to improve the waterproof property of the housing of the LED lamp, but in this case, the heat radiation property of the housing is poor due to the one-piece housing of the LED lamp.
In view of the heat dissipation of the housing of the LED lamp, a corn lamp is proposed, as shown in fig. 2, in which each LED chip strip is enclosed by a separate housing, however, this increases the possibility of failure of the LED lamp due to the penetration of moisture and/or water by the cracks at the junction of each separate housing.
The inventors of the present application evaluated the closed design of the conventional LED luminaire of fig. 1, and found that such a design had poor thermal performance and high cost. Then, the inventors of the present application further evaluated the waterproof design of the lighting device shown in fig. 2, and found that the LED lamp of fig. 2 has a poor waterproof effect.
Further, in the prior art, in order to solve the heat dissipation problem and the waterproof problem of the LED lamp, chinese patent publication No. CN103910987a discloses an integrated LED lamp housing including a heat radiation portion and a light transmission portion, thereby improving the moisture-proof and/or waterproof property of the LED lamp housing and the heat conductive property of the LED lamp housing. Further, korean patent KR100949106B1 discloses a lamp housing of an LED lamp, which includes a light transmission part formed at one side of the lamp housing and a heat dissipation unit formed at the other side of the lamp housing. However, since the LED lamp housings disclosed in these two prior arts are still integrated as shown in fig. 1, the thermal conductivity thereof still needs to be improved. And since the lamp housing is an integrated LED lamp housing including a heat radiation portion at one side and a light transmission portion at the other side, it actually sacrifices light transmission efficiency in exchange for heat radiation performance, and thus, the integrated LED lamp housing has poor light efficiency.
The main purpose of this application is to obtain waterproof function when not reducing the optical efficiency of LED lamps and lanterns, still keep good heat dispersion simultaneously.
